See her blog post:  https://dataswamp.org/~solene/2024-07-24-openbsd-email-server-setup.html : This blog post is a guide explaining how to setup a full-featured email server on OpenBSD 7.5. It was commissioned by a customer of my consultancy who wanted it to be published on my blog. Setting up a modern email stack that does not appear as a spam platform to the world can be a daunting task, the guide will cover what you need for a secure, functional and low maintenance email system.

You're greeted by a rather shabby alabaster cast of this marble:  See  Fragments of a marble statue of the Diadoumenos (youth tying a fillet around his head) . Apparently his eyes are averted, meaning that he wishes to be admired. I thought about the process of making a carving like this and what was involved in an age where any perception of a living thing was abstracted out of one continuous movement. They had no photographs in those days! See  Hannah Fry on Mind Reading .

She's equating how somebody is feeling with a judgement about their conscious state, or even their conscious intention, isn't she? That's not necessarily wrong, but I wonder if how we are feeling might also be due to something beyond just what we consciously perceive. Subscribe to Hannah Fry .

See  https://feertech.com/microbeast/ This is an 8 bit kit with the the following design goals: A complete, self-contained 8-bit computer kit that can be built without specialist tools. Genuine 8-bit design, don't cheat with "support" processors that are more powerful than the main CPU. All development, from applications to firmware, can be done without expensive or obscure tools. Use standard connectors. No odd or outdated adapters adding to clutter. Use only currently manufactured and available components. 8 bit shouldn't mean obsolete. Can be expanded, customised and hacked - with full access to the CPU bus. Intentional, honest design - make choices, not excuses. Keep costs down, but don't cut corners. The result is this: Self contained 8-bit computer kit in a box Unique 24 character, 14 segment display & virtual console 47 Key keyboard Z80 CPU 8-10Mhz 512K RAM, 512K Flash ROM Power and data over USB C Battery backed Real time clock Running CP/M 2.2 GPIO H

See  Modelling Dynamics of Dissipative Systems This is one of the problems. My AI-trained brain says that it's about Galois Connections and Fourier Series, for what I imagine are obvious reasons. That's just by fuzzy pattern recognition on lambda abstractions. Speaking of lambda abstraction, I just noticed something on the thumbnail of David Turner's lecture that's quite radical: call-by-value is not correct! That's a more striking way of saying that it is not normal forms, but head normal forms that are important. There is a connection to solvability . Subscribe to The Looking Glass Universe .

Thinking about Jack Wisdom's comment at the end of his MIT Earth, Atmospheric and Planetary Sciences Chaos and Climate talk on Chaotic Dynamics in the Solar System: The tides on earth are coupled to the Solar System dynamics and I was wondering how to describe this mathematically. On Earth the tidal energy is dissipated by an array of more or less  synchronised rotational oscillations. See  Dynamic Theory of Tides : The result of all of this is that instead of a simple standing wave moving back and forth across the ocean, the tidal crest follows a circular pattern around the ocean basin, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. This is analogous to shaking a pan full of water in a circular manner, and watching the water follow a similar circular path as it sloshes around inside. This large scale circular rotation pattern of tides is called amphidromic circulation (Figure 11.2.4). The rotation occurs around a central amphidromic point o

Indeed! Subscribe to ACM SIGPLAN . But what if you can't even get an interpreter for your language to run? Sussman said something like "The specifications aren't handed down from the boss. Usually they come from an assessment of what is possible, ..." So it all hinges on the judgements programmers make about what is possible. Scheme is a community of sorts, see  https://standards.scheme.org/ and it has a kind of meta-community in the form of something called the  SRFI process . SRFI stands for Scheme Request For Implementation. Since around the year 2000 the number of requests has ballooned and there are now over 250 of them. The first twenty or so concerned language features and very widely useful libraries for strings, sets and so forth. The SICMutils package is a Clojure implementation of  scmutils , which is a kind of generic algebraic computation library. It relies heavily on a feature unique to MIT/GNU Scheme called Application Hooks . This is a feature by whi
